Does anyone know the differences between the (far more expensive) 2
part epoxy garage floor paints vs. the less expensive 1 parts(no
mixing)? I recently bought a Quikrete 2 part epoxy floor paint kit for
my garage. The kits are around $60, but you can't buy the paint alone!
I needed 3 more gallons and would have had to buy 3 more kits. SO, I
saw right NEXT to the Quikrete kit, a product also made by Quikrete
called "seal-krete" for garage floors and other concrete surfaces. It
claims to be "one part epoxy" and makes very similar claims about
durability, heat resistance, etc. This paint sells for $25/gallon. So,
I bought the closest color match and have almost finished the floor. I
painted over the remaining "good" epoxy paint after it had cured for
about 12 hours (hope the new stuff sticks OK).
Admittedly, it seems the two part was thicker, glossier, etc.
Interestingly enough it also didn't cover nearly as much space per
gallon as the cheaper paint did. I just wonder how the MFG can make
nearly the same claims about these two different types of paint. How
does the epoxy even work in a 1 part kit? I always thought epoxy
required "activation" as in the 2 part kits. Any ideas/experience on
this would be appreciated. Thank you!
You would have been happier with the 2 part epoxy paint. Too bad you were
too cheap to use it. In short, it can't be epoxy if you don't have an
activator to mix in to it. Epoxy paints harden via chemical reaction, they
That said, I painted my garage floor with regular oil-base "porch and floor"
paint years ago before this epoxy paint became all the rage. It held up
well to foot traffic and some types of damage. Snowblower chains and
hot-tire pickup have been a problem though. It will make you a nice floor,
it just won't be as durable as epoxy.
The two part is more durable and a better choice for a garage floor. Of
course there are some better and some worse of both types and the most
important thing with either is the prep work. If you don't do the prep
right, you are wasting your time and money with either type.
I agree about good prep work, but I think it's more important with the one
part stuff. The hardener in the two part epoxy is a catalysis that creates a
chemical reaction which generates heat and actually (for lack of a better
term) welds the epoxy into the surface.

I have used both kinds, by different companies. My honest opinion is
that they all suck. I spent two days preping one garage with a two
part epoxy, the client was in Europe for a month. and when they
returned, they got tire pick up on the floor.
If you have the bucks, put down carpet - the comercial washable kind.
Never had a call back on that install...
I would have to suggest, that while you spent the time on prep,
something was not right. Maybe the prep, maybe the product maybe the
application. It is clear from my personal experience and the experience of
many others here, that done right with the right product there is no tyre
I wonder if there could have been some sort of problem with the
concrete. I have seen the recommendation not to use it on concrete that is
not fully cured. How old was that concrete when you did the job?
NO PAINT OF ANY TYPE holds up well. I think your much better off to
never paint a garage floor, and once it fails bite the bullet and
strip, power wash or sandblast all the paint off returning it to
natural concrete. then seal with thompsons water seal or ssomething
similiar. so goo cant get into the concrete.
they also have big rubber sheets that are rolled over the floor.
paint is just a continius maintence chore.
just like painting cement block or worse yet brick its a terrible
I agree. The only time painting a garage floor works is if the only thing
done in a garage is parking a car. But if you do anything else, like repair
change your oil, work on your bicycle, drag a washing machine across the
floor, run a table saw, etc. it scratches the paint and then looks like
The only time I ever saw painted garage floors look half-decent is when
I was visiting my grandparents in Sun City AZ years ago.. All of them have
floors down there but nobody living there does anything other than park
a car and a golf cart in the garage.
Mine still looks good and I park two cars, work on them, change their
oil, work on three bikes (one Honda two peddle powered) and I have a radial
arm saw I use in there. I have not moved a washing machine across it
however. Maybe it is the washing machine. :-)
I woould not buy anyo of the stuff at big box places, they do not have
Have said before: Ben Moore industrial coatings, they make both 1 part
and 2 part epoxy, both are good, 2 part is better.
ALWAYS etch, always cured concrete MINIMUM 60 days
Thanks. I think I must not have been clear in the post. What I'm still
curious about is all this 1 part 2 part stuff. Here is the data on the
cheaper product I used http://www.seal-krete.com/epoxyseal.htm
The "better" 2 part product is here
There is roughly a $35 difference in price per gallon between these two
products. The more expensive one does include the "kit" which gives you
the cleaner/etcher. Of course, you only need a bottle of that to do an
entire two car garage. You'll need at least 3 gallons of the paint
(unless you know some way to lay it down thinner than I was). Yes,
that's around $200 with other materials for a very small garage! This
of course includes no labor assuming you are doing it yourself.
My point about all this is that it's quite confusing. If there is such
a large difference in price, I'd like to know more details on why? Yes,
the two part product "cures" on the crete. The one part "dries" ... or
does it "cure"? Honestly, I don't know the answers, and so far the
replies I have received seem the like the advertising - lacking
specific information about the strengths of the two part over the one
part. The only obvious difference I've seen is the glossy thick coat
the two part puts down compared to the one part. However, I put down a
satin finish for the one part vs. a semi-gloss for the two part. While
I'm sure the two part "thickness" is stronger, I have no idea how much
better it is actually bonding to the concrete. I guess only time will
tell. I plan to call the mfg's on both these products to see if I can
get any more specific information. Namely, what the "epoxy" component
really is in the one-part product.
Has anyone messed with clear epoxy topcoats over the paint? I'm
thinking about it, but again do not know if that would in fact weaken
the paint with more than one layer. Another question that pops up is UV
resistance. Ironically the more expensive two-part makes no claims
about this. I was thinking about using one of the two-part kits to
paint my back porch (it's very small), but not sure if the sun would

You can get epoxies that are one- or two-part. The two-part cure when the

There's nothing on the Seal Krete web site that tells me what kind of curing
takes place with
the one-part. It could be that there's an inhibitor in the mix that evaporates
painted on. Maybe the reaction only works in the presence of oxygen. Maybe
it's not a
a true epoxy, but a resin that air cures.
As far as why one is more pricey than the other - in general, the better
coatings cost more
and the more they cost, the better they are. Two-part coatings are almost
more expensive and more durable than one-part. I have two friends in the
one an epoxy expert (chem. engineer) the other a coatings and adhesives
(chemist). I've bugged both about this stuff quite often. They tell me that
prices reflect the higher material and manufacturing costs.
That some manufacturers/retailers may rip people off is another issue.
mike is right. I am in the epoxy business. Note that epoxy floors can
go from a 1 coat to a 7 coat system (with primers, colored chips, clear
